3 Claims.

This invention relates to seats and particularly to those used in airplanes, railroad coaches and other vehicles of the type in which seats, usually two in number and independently adjustable, are arranged side by side.

An object of this invention is to provide an improved construction and arrangement of this type of seat, in which a removable arm rest is provided between the adjacent seats having an improved connecting means of such simplified construction as permits the ready assembly or disassembly of the arm rest as may be required.

This and other objects which will be apparent are accomplished by the invention hereinafter described and illustrated in the accompanying drawing in which,

Fig. 1 is a perspective view of a vehicle seat having a detachable center arm rest constructed in accordance with one embodiment of this invention, and

Fig. 2 is a side elevation, partly in section, of the center arm rest shown in Fig. 1.

As illustrated, the invention is shown in connection with a double passenger seat having two independently adjustable seat and back frames 5 and 6 mounted on a supporting frame 1 of tubular members including front and rear legs 8 and 9 and side arms I0 and II at each side of the frame.

Each seat and back frame is independently adjustable, each back being pivotally supported on a rear cross rod I2 while each seat is slidably supported on a front stretcher I3, a handle I4 being arranged on each seat to control a locking mechanism, not shown, for holding the seat in adjusted position.

In the present invention, a tubular center front The open end of the rear leg is closed by a plug I I secured in the leg by a screw I8 or other means and projecting outwardly beyond the end of the leg. A detent I9 having a spring pressed point 2I is secured in a radial bore in the plug I'I.

A detachable arm rest 22 has a vertical front end 23 in which a plug 24 is slidably mounted, a radial pin 25 being secured in the plug and extending outwardly through aslo'rl 25 in the wall of the arm 23. The opposite end 2l of the detachable arm rest is formed at the same angle as the upper end of the rear leg I6, and can be telescoped over the rear leg plug Il to abut the upper end of the leg I6, whereupon the spring detent 2I snaps into an opening 28 in the Wall of the arm to hold the parts yieldingly together.

When assembling the detachable arm rest, the rear end is connected to the rear leg in the manner described, the plug 24 in the vertical iront end rst having been withdrawn into the arm by lifting the pin 25 to the top of the slot 2B. When the arm is thus placed in position with the rear arm plug Il telescoped within the open rear end of the arm, the front vertical end of the arm will abut and rest upon the open upper end of the iront leg I5, whereupon, by releasing the pin 25 lowering the plug into the leg I5, the arm 22 will be detachably locked in place. For removal, it is only necessary to lift the front plug 24 to free the front end of the arm and permit the rear end to be drawn off the rear plug Il against the tension of the detent I9.

The detachable arm is shown as having a cushion 3| and an ash receptacle 32.

It will be apparent that the invention can be variously modied and adapted within the scope of the appended claims.

What is claimed is:

1. An article of furniture comprising in combination, a supporting frame including front and rear legs formed by tubular members, a tubular arm rest, means removably connecting one end of the arm rest to one of the legs and comprising a plug slidably mounted in said one end of the arm rest and movable into telescoping engagement with said one of the legs, and means for preventing rotational movement of the plug with respect to the arm rest, and means connecting the other end of the arm rest to the other leg.

2. An article of furniture comprising in combination, a supporting frame including a front leg and a rear leg formed' by tubular members, a tubular arm rest, means for removably mounting said arm rest on said legs, said means including an arm-engaging plug projecting outwardly from one of said legs and adapted to engage within one end of said arm rest, a connector plug slidably mounted in the other end of said arm rest and movable into telescoping engagement within the other of said legs, and a pin carried by said connector plug and extending through a slot in said arm for lifting said connector plug out of said other of said legs to disconnect said arm rest therefrom.

3. An article of furniture comprising in combination, a supporting frame including a front leg 3 formed by a, tubular member extending substantially vertically upward and a rear leg formed by an upwardly extending tubular member having a forwardly extending end portion, a tubular arm rest, means for removably mounting said arm rest on said legs, said means including an armengaging plug projecting outwardly ffrom'the forwardly yprojecting end portion of said rear leg and adapted to engage within one end of said arm rest, a detent carried by said plug for engaging a recess in said arm, a connector plug slidably mounted in the other end of said arm rest and movable into telescoping engagement within the upper end of said front leg, and .a pin v,carried by said connector plug and extending through a slot n said arm rest for lifting said connector plug out of said front leg to disconnect said .arm rest therefrom.
